BACKGROUND OF THE INVENTION Field of the Invention

The invention generally relates to a medical device, method and systemthereof for the placement or passage of patches, sutures, anchors, tags,tissue sensors and more particularly to a medical device for repairingfemale pelvic organ or tissue prolapsed region.

Discussion of the Related Art

It is estimated that nearly twelve percent of women will need surgeryfor pelvic organ prolapse. Historically, the long term result of thesesurgeries using the patient's own tissue for the repair, has beendisappointing for both the patients and the surgeons. Recurrence ofprolapse after standard autologous tissue repairs has been reported tobe as high as about thirty percent to about forty percent.

Many current methods for pelvic reconstruction use instruments designedfor laparoscopic surgery. These devices allow the surgeon to suture oranchor tissue, or to staple a patch or graft material into place. Whilelaparoscopic instruments may be effective for laparoscopy when usedunder direct visualization, they tend to be less effective when usedused in conditions of limited space and visualization, e.g., the vagina.More specifically, when laparoscopic instruments are used for vaginalsurgery, there is a lack of tactile assistance or feedback when workingfrom the end of an instrument. In addition, laparoscopic instruments arerigid and therefore not suited to the angles and planes encountered invaginal surgery.

Methods, techniques and devices were developed that use a perinealapproach. In these techniques, needles or carriers are placed throughthe skin of the perineum (outside the vagina) and into the pelvis andvagina. Once in position, graft material is attached to the needleswhich are drawn brought back out to the external skin, pulling the graftinto position.

Moreover, these related art instruments are difficult to use with aperineal approach. Moreover, as the perineal approach is not widelytaught, or familiar to many surgeons it is not a general skill of mostsurgeons, and it requires passage of a needle/carrier blindly through agreat distance of tissue. Therefore, the difficulty of these techniquesand related art devices limit their use to a very few specialists whoare able to perform them, thereby limiting the availability of thetreatment. Furthermore, this percutaneous approach has resulted inadditional possible surgical complications, including infections,surrounding organ injuries, and painful scarring.

Other currently available methods and instruments available use a moretraditional and familiar vaginal approach. These are generally sold as akit, which include rigid devices used to aid in the attachment of graftmaterials. The graft is preformed and specific to the repair being done,i.e., anterior, posterior or apical. Currently available methods andinstruments for the vaginal approach to prolapse repair utilize surgicalskills and anatomical landmarks familiar to most gynecologists. However,the cost associated with the kits, the generally rigid and unwieldynature of these devices render these kits problematic.

Therefore, there is a need for a device, method and/or system thataddresses the above and other problems.

Reference will now be made in detail to an embodiment of the presentinvention, example of which is illustrated in the accompanying drawings.

FIG. 1 illustrates a flow diagram highlighting aspects of a methodaccording to an embodiment of the invention.

Referring to FIG. 1 , the method is generally depicted as reference 100.The method includes creating an incision 102 at a desired situs, e.g.,anterior vaginal mucosa, posterior vaginal mucosa, or vaginal apex. Itis noted that the device and method may be used at other locations andfor other uses. For example, the device may be used for setting markersor tags in orthopedic and neurosurgical procedures where navigationsystems are used to guide placement of implants and the like. The mucosais dissected 104 sharply and/or bluntly away from the underlyingconnective tissue plane (endopelvic fascia). Deficiency or breakdown ofthis connective tissue layer is what allows the prolapse and bulging ofthe vaginal walls and underlying pelvic organs into the vagina to occur,i.e., the bladder from anteriorly (cystocele), the rectum fromposteriorly (rectocele), the uterus or intestines from superiorly(uterine prolapse or enterocele), on the vaginal walls from laterally(paravaginal defect).

The connective tissue plane can be traced to the pelvic side wall wheresubstantial ligamentous and fascial structures exist and serve aslandmarks and anchor points 106. The mapping may be done while thedevice is being used by the user, e.g., with one or more finger tips.After a map of the surgical area is developed, the device on two or morefinger(s) is inserted the device into the vagina 107. The device isarranged on a co-axial orientation to an axis of the arm and/or hand toaid in orientation. Anchors and sutures are generally set into thesacrospinous ligament, arcus tendentious, obturator fascia and coopersligament 108. Following this plane through a small vaginal incision tothe pelvic sidewall is a basic gynecologic surgical maneuver. Once thisplane is developed for the patient, the anatomical landmarks are easilypalpable and the sacrospinous ligament, arcus tendineous, Cooper'sligament and obturator fascia are easily identified though verydifficult to visualize.

The device may be used with surgeons' second and third fingers to aid inlocation and placement to a desired location on the pelvic wall andthese fingers provide tactile feedback via an exposed fingertip.Moreover, as the sheath utilizes at least two fingers the orientationthe stability of the device is readily maintained, e.g., middle fingerand the ring finger; index finger and middle finger; or little fingerand the ring finger. In this preferred embodiment, the user aligns thedevices via their fingers, hand, and/or arm to ensure proper placementwithout sight. The device is not offset from fingers, hand, and/or arm,e.g., along a central axis, thereby allowing alignment even though thereis no visualization.

Next, an anchor, with attached suture, is delivered from the deviceexactly to the desired location by pushing the button at the oppositeend of the device. In a preferred embodiment, this is done while thesurgeon is still in contact with the pelvic wall. With the anchorexposed, and pressure delivered 110 at the closed finger-tip end, thedevice will set the anchor into the tissue at the desired location inthe pelvic wall. In a preferred embodiment, the anchor and mesh areconfigured to repair, secure, or reattach the underlying connectivetissue, or anchor graft material that substantially supports theprolapsed organs.

Optionally, sutures may be attached to these anchors and can be used tosupport the vaginal wall itself, with or without the use of a graft.With the safety of vaginal mesh under scrutiny by the FDA, many surgeonsare returning to use mesh-free repairs. The device described hereinwould make those procedures much easier.

Alternatively, anchors and sutures in the sacrospinous ligament, arcustendentious, obturator fascia and/or coopers ligament could also be usedto suture graft material over the deficient connective tissue plane fora graft augmented repair. Alternatively, anchors without sutures may beused to directly tack graft material to the desired location.

In still other embodiments, the operating unit of the device may bemodified with devices known in the art. For example, the operating unitmay include a scope to give active visual aid to the surgeon. In anotherexample, the operating unit of device may include a endoscopic suturedevice or anchor device configured to secure the graph or support anprolapsed area. By way of example, the endoscopic suture systems may beincorporated in the operating unit and include systems as known in theart, e.g., as disclosed in U.S. Pat. Nos. 5,364,408; 5,458,609;5,478,344; 5,540,704; 5,575,800; 5,578,044; 5,662,664; 5,700,272;5,713,910; 5,741,277; 5,741,279; 6,048,351; 7,582,096, and U.S. PatentApplication Publication Nos. 2010/0217282; 2011/0092985 and2011/0092991, all of which are herein incorporated by reference.

The suture device may be used in laparoscopic procedures. The suturedevice, and in particular the head of the device, may be used with thepresent invention by attaching the head of the suture device to thefinger sheaths of the present invention. In general, the suture deviceautomatically throws, catches and retrieves a suture through the head ofthe device. An example of a suture device is described in U.S. Pat. Nos.5,741,277 and 7,582,096, which are incorporated herein by reference.

FIG. 2 illustrates a perspective view of an endoscopic suture deviceaccording to an embodiment of the invention.

Referring to FIG. 2 , an apparatus is generally depicted as referencenumber 200. The apparatus 200 includes a connection mechanism 202 fixedto an end portion of the tubular member 204. A finger sheath (notshown), described with reference to FIGS. 7A-15 is utilized with thisdevice 200 and configured to be coupled to the device 200 via theconnection mechanism 202 as described with reference to FIGS. 13-15 .

The apparatus 200 includes the body 204 having a first half 206 and asecond half 207. A needle slot 208 is utilized to deploy a cannula 210out of the cannula body 204. The cannula 210 can be utilized with otherinstruments as known in the art. For example, the cannula 210 isutilized to deploy a needle and sutures (not shown). Alternatively,other secondary devices may be delivered through the cannula 210, e.g.,visualization devices.

FIG. 3 illustrates a perspective view of a needle catch mechanism with aneedle and a phantom view of a cannula body according to anotherembodiment of the invention

Referring to FIG. 3 , the suture system is generally depicted asreference number 300. The suture system includes a first half 302 and asecond half 304 configured to form a body 306. The system 300 includes aconnection mechanism 305 fixed to an end portion of the tubular member306. A finger sheath (not shown), described with reference to FIGS.7A-15 is utilized with this device 300 and configured to be coupled tothe device 300 via the connection mechanism 305 as described withreference to FIGS. 13-15 .

A surgical needle 308 includes a needle tip 310 and a needle body 312,and a suture 314. A retainer lever 316 is pivotally mounted on a shaft318 and is biased to a neutral position by a spring 320 or othersuitable mechanism. A needle guide track terminates in an exit opening322. A flexible needle driver guide track and the needle guide trackcombine to form a continuous pathway in which a flexible needle driverwith a needle driver tip is slidably disposed. The needle 308 isinserted through the exit opening 322. The needle 312 and the suture 314are inserted into the needle guide track until the needle tip 310 ispositioned adjacent to the exit opening 322. It may be seen that duringinsertion into the needle guide track, the needle 308 causes theretainer lever 316 to rotate pivotally on the shaft 318 to a retractedposition. In operation, an actuator (not shown) is operated to advancethe needle 308.

To retrieve the needle 308 and the suture 314 the cannula body 306 isplaced in the surgical field and maneuvered to guide the needle tip 310and needle shaft through an opening in a needle catch, which includesthe opening and a catch bottom. The flexible needle driver is advancedin the needle guide track, engaging and pivotally rotating the retainerlever 316 and pinching and capturing the needle body 312 between theretainer lever 316 and a catch bottom. The needle 308 and the suture 314may then be removed from the surgical field through the surgical trocaror other suitable instrument. To release the needle 308 from beingpinched by the retainer lever 316 and the catch bottom, the flexibleneedle driver is retracted, allowing the retainer lever 316 to return tothe neutral position, thus freeing the needle 308.

In still other embodiments, an apparatus such as a suture device may bemodified with aspects of the invention including a finger sheath andconnection mechanism to provide a device that allows for advantages ofthe invention. Examples of devices that may be modified are disclosed inU.S. Pat. Nos. 7,828,189; 7,828,798; and 7,789,878; and U.S PublicationNos. 2010/0094083; 2010/0217282; 2010/0274265; 2011/0040308;2010/0147921; 2006/0036232; 2009/0248046; and 2009/0259233, and are eachincorporated by reference, in particular, the portions of thedisclosures describing the head of the endoscopic stitching device. Morespecifically, each of the foregoing may be modified and adapted for usewith a connection mechanism 305 fixed to an end portion of any of theforegoing devices. A finger sheath (not shown), described with referenceto FIGS. 7A-15 is utilized with this any of the foregoing modifieddevices and configured to be coupled to the device via the connectionmechanism 305 as described with reference to FIGS. 13-15 .
